I've also got the ghost of some conversation running around in my head claiming that the location grid function is deprecated, but I couldn't say when I've heard it, from whom and whether it's true or not ;)
Reworkign pyWPS to create a location on the fly is a really interesting idea ;) But I'm a little bit confused as to what you have planned - are you wanting to do an analysis with r.sun for different rasters at runtime and show them on demand? I would suggest running r.sun beforehand and storing the result, since r.sun can take a long time with larger areas. Cheers, Daniel
